In the opening scene of the movie Raiders of the Lost Ark, Indiana Jones replaces a golden statue with a bag of sand. The platfo

rm on which the statue is placed is designed to detect the mass of the statue. If the bag of sand has a different mass than the statue, then a mechanism triggers and destruction ensues.

Answer:

1920π

Step-by-step explanation:

First, you need to find the volume of the statue in terms of pi.

Volume of cylinder formula:

V=πr²h

V=π4²15

V=π16×15

V=240π

Then, you need to find the mass of the statue.

Mass:

Mass= density × volume

Mass=20×240π

Mass=4800π

Now, you need to find the volume. Since the sand has to weigh the same as the statue, the mass is going to stay the same. To find the volume you need to do:

V=mass of sand/density

V=4800π/2.5

That gives you your answer:

1920π

Note: I had to do the exact same problem on Khan Academy. This is right.

please answer this A bicycle store costs $2400 per month to operate. The store pays an average of $60 per bicycle that is sold i
mezya [45]

Answer: The store must sell 40 bikes.

Step-by-step explanation:

y=60x+2400

y=120x

120x=60x+2400

-60x on both sides

60x=2400

divide 60 on both sides

2400/60=40

x=40

5(x + 3)= 4(x -3) <br> What is x?
lana66690 [7]

Answer:

-27

Step-by-step explanation:

5(x+3) = 4(x-3)

5x + 15 = 4x - 12

5x - 4x = -12 - 15

X = -27

DochEvi [55]

It should be noted that the value of 597 subtracted from 884 is 287.

<h3>How to illustrate the subtraction?</h3>

The information is simply that we should subtract 884 and 597 and also illustrate it.

This will be:

884 - 597 = 287.

A word problem illustrating this is that a man had 884 pens and gave 597 pens to his friends. How many pens does he have left?

This will be:

= 884 - 597 = 287

In order for a ladder to reach a height of 10 feet, it needs to be placed at a 75° angle to the ground. The ground already has a
Dmitry [639]

Since the ground already has an elevation of 15 degrees, the ladder needs to

be set at 60 degrees to reach a height of 10 ft.

In order for a ladder to reach a height of 10 feet, the ladder needs to be

placed at 75 degrees angle to the ground. This is when the ground has no

angle of elevation or when it flat.

Now, if the ground has an angle of elevation of 15 degrees , the degrees in

angle the ladder needs to be set can be solved as follows:

<h3>Angles in degree: </h3>
  • 75  - 15 = 60 degrees

Therefore, the ladder needs to set at an angle of 60 degrees if the

elevation of the ground is already 15 degree. The elevation of the ground

will complement the angle in degrees required for the ladder to reach 10

feet.
